Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Pat the extra firm tofu dry with a clean towel to remove excess moisture and cut it into 1/2-inch cubes.
In a large mixing bowl, combine the tofu cubes, chickpeas, and broccoli florets.
Drizzle the mixture with olive oil and sprinkle with garlic powder, smoked paprika, sea salt, and black pepper, tossing until evenly coated.
Spread the ingredients in a single layer on the prepared baking sheet and roast for 25 minutes, or until the tofu is golden and the chickpeas are slightly crunchy.
While the vegetables roast, place the fresh spinach and warm cooked quinoa in a large serving bowl.
Top the greens and grain base with the roasted tofu, chickpeas, and broccoli.
Garnish the bowl with nutritional yeast for a cheesy flavor boost and drizzle with fresh lemon juice before serving.
